The Whadda WSAK201 is the cutest solder kit to save your house plants.
This panda shaped gadget has gold plated contact points or probes that can measure the humidity of a plant's soil. The kit is very easy to assemble and once finished, you can simply stick it into the soil of your favourite houseplant. The bright RGB LEDs that mimic the panda's eyes will light up every 30 seconds to show the status of the soil. The soil is either too wet, too dry or perfect. A word of advice; you do not want the panda to stare at you with fiery red eyes so keep your plant happy!
Because each plant has different needs, we added two thumb wheels to adjust the sensitivity. The right wheel adjusts the distance sensitivity and the left wheel enables you to adjust the moist sensitivity. There will be no dead plants on this panda's watch!
The kit is powered by two CR2032 batteries (not included) and they'll keep the panda alive for at least two whole months.
Gold plated contact points or probes that measure the moisture level
2 x thumb wheels to adjust the range and sensitivity
2 x RGB LEDs that indicate the moisture level every 30 seconds, green: perfect soil, red: too dry, blue: too wet
Ring in the summer with this Whadda WSAK204 electronic cicada soldering kit.
The cicada consists of three PCBs to mimic the shape of this popular insect as best as possible. The body is matt black and the two wings are shiny yellow with golden tracks. To finish off the design, you can use the included components to add legs to the cicada. This way, it will have a real-life look!
So how does it work? There's an on-board phototransistor that makes the buzzer sound when it's dark while an orange LED flickers along. You'll have everybody fooled!
The bug is powered by a 9 V battery (not included) which will last about 30 hours when constantly in use.

Included
WSI102: FLASHING LEDS SOLDERING KIT
suited for different applications (e.g. model construction) and also educational. Adjustable flashing speed with two potentiometers.
WSL104: SOUND-TO-LIGHT UNIT
Four high-intensity LEDs light up and react simultaneously to every sound. For different funny and practical applications e.g. sound indicator, simple sound-to-light unit for music. The unit can also be used to indicate when the doorbell or the telephone is ringing, which is particularly interesting for the hearing-impaired. Adjustable sensitivity with potentiometer. Built-in microphone.
The Whadda WSG101 Madlab Electronic E-Lock kit is an electronic combination lock that is controlled by your mobile phone.
The E-Lock picks up, using the onboard microphone, the DTMF tones generated when the keypad of a mobile phone is pressed. When the correct combination of keys has been pressed, the E-Lock's 1 amp integrated relay is activated.
The relay can be connected to a solenoid (not supplied), or other device, controlling the lock on a door or enclosure.
The Whadda WSG102 Madlab 1-2-3 is a game of logic that pits you against the machine. The game's "logical thinking" is hardwired without using a microcontroller. It's all diodes, transistors and LEDs.
Easy to play. Not so easy to win. You play by moving a peg along a path of holes. Players move alternately, and on each turn a player can move the peg 1, 2 or 3 spaces (hence the name). The player who moves the peg to the final hole is the winner.
The Whadda WSG104 Bagpipes is an audio oscillator kit similar to the MadLab Electronic Kit - Wonky Wire.
The Bagpipes kit is, however, capable of producing eight different tones from approximately 5kHz to 300Hz.
To use the Bagpipes, the stylus wire is moved up and down the network of resistors R1 to R8 which make up the keyboard. The voltage at the end of the stylus changes as each keyboard resistor is touched in turn.
The Theremin was the first music synthesiser. The Whadda WSG105 Junior Theremin is our, smaller, version of that classic electronic musical instrument. As you move your hand towards and away from the wire aerial, the Theremin responds by changing the pitch of the note it is playing. It can play individual notes as well as varying the tone of a single note.
How do you use the theremin?
The wire aerial responds to the movement of your hand towards and away from it and changes the pitch of the note it plays, without actually being touched.
Junior Theremin works in two modes - continuous and discrete. When you first connect the battery Junior Theremin is in continuous mode. Pressing both pushbuttons together switches between continuous and discrete modes. Discrete mode, as its name implies, plays individual or discrete notes rather than a continuously variable tone.
Eight notes over a single octave are available. In discrete mode the two pushbuttons change the octave of the notes. The left-hand pushbutton (marked -) lowers the octave, and the right-hand pushbutton (marked +) raises the octave.
The pushbuttons only change the octave so long as they are pressed. In continuous mode the pushbuttons have no effect.
The Whadda WSG106 Lie Detector works by measuring galvanic response. In other words, when a person lies, they tend to sweat. Perspiration has a high sodium content, so sweat is conductive. Dry skin has a resistance of about 1 million ohms, whereas the resistance of moist skin is reduced by a factor of ten or more.
A person holding the probe wires will change the voltage at the upper probe wire depending on their skin resistance. The skin resistance is in parallel with R2 and, because it is likely to be similar to or smaller than R2, the voltage at the probe wire will fall as skin resistance falls.
With the Whadda WSG109 you can learn or practice Morse Code with this electric telegraph. This electronic kit is a modern version of one of the earliest forms of electronic communication, the Electric Telegraph. The original Electric Telegraph utilised the "dot dash" code invented by Samuel Morse.
When you become skilled and fast enough, two of the Electric Telegraph kits can be wired together and messages can be sent back and forth between two telegraphers.
The Whadda WSG110 Wonky Wire is used to test the steadiness of your hand.
It utilises a circuit with an oscillator that has a very high oscillation frequency of about 3kHz (3000 cycles per second). As you try to trace the outline of the wire with the loop, the slightest touch will cause a tone to sound. The variable resistor can be used to change the pitch of the tone.
The Whadda WSG111 is a remake of the classic carnival and arcade game, the Whack A Mole.
The first game is to test your speed, reflexes and reaction time. When the moles light up react as fast as you can and "Whack the Mole". The second game is Moley Says, to test your memory. Memorise and then repeat a sequence of lights.
The Whadda WSG112 Brain game provides hours of fun from just 4 LEDs and push buttons.
The objective of the game is to repeat a randomly generated pattern. The pattern is played both visually and audible or visually only. It features 4 difficulty levels, which can be selected at start-up. The replay speed gradually increases during the game, to make it even more challenging.
Do you find it annoying when you're playing a board game and roll the dice on the board, and push all the pieces on the board? Or if you suspect that a friend is cheating by manipulating the dice?
With the Whadda WSG150 all these problems are solved with this mini kit. Unlike its little brother (the MK109), you can activate this dice, not with a push button but simply by shaking it.
Uses a lithium battery (not included).
Push buttons not required, just give it a shake

The Whadda WSL103 Atom Heart kit is our Cyberpunk version of the Iron Man® ARC Reactor®.
Now you can give your Teddy Bear, or other favourite doll or stuffed animal, their very own Atom Heart. The slits in the PCB (printed circuit board) can be used to attach the kit to anything you want. The light patterns of the Atom Heart can be changed by pushing the button.
The Whadda WSL107 My Little Alien is a funny and creative solder kit that is very easy to assemble.
The entire kit consists out of only 4 components, which makes it the ideal solder kit for beginners. The two RGB LEDs (Red Green Blue) will resemble the eyes of a real extraterrestrial.
Once you have soldered all components, you can melt the supplied polymorph granules in hot water to make them stick together. Take the melted polymorph and form it into whatever shape you desire, then place it over the LEDs. Once the polymorph sets, it will give your little alien a very "other worldly" light diffusing effect.
The Whadda WSL108 Mr. Robot (AKA Robotto-San) is a wearable electronic gadget that you can pin onto your t-shirt or jacket.
This kit is a fun gadget that is easy to solder. The flashing LEDs resemble the eyes and the red PCB (printed circuit board) has the form of a little robot.

This compact Whadda WSMI7102 metal detector can be used to find electric cables before drilling a hole.
Likewise, drilling into gas, water pipes or central heating pipes can be extremely hazardous. With a handy metal detector it can now be determined beforehand whether there are metal objects to be found in a wall, ceiling or floor. An LED indicates if a metal object is in the vicinity.
Avoid disasters when drilling holes in walls.
Locate pipes, cables, metal studs.
Great project for novices.
Your own unique application.
Simple push button operation.
Hints and Tips
If you experience difficulties with the calibration of the unit (ie if the LED doesn't turn off, when there isn't any metal present ), replace C1 with a ceramic 1.2nF (122) capacitor. This behaviour is due to a spread on the component values and differences created when winding the coils.
For those wanting an audible signal, space is provided on the print for connecting a buzzer type SV4/12-S. The small PCB has been specially designed to be incorporated into a separately available project 120 x 60 x 30 mm.
Test your love with this Whadda WSSA149 love tester.
How does it work? Each partner holds one end of the heart pcb and holds hands. Your love level is indicated by 10 flashing LEDs and a buzzing noise. The more LEDs flash and the faster the buzzer sounds, the more you like each other.
